| Summary: | Introduction. Choroidal coloboma is a congenital defect caused by an
inadequate closure of embryonic fissure. About 40% of the eyes with the
choroidal coloboma (CHC) develop the retinal detachment (RD). It is extremely
difficult to manage these cases due to the lack of pigmentation at the site
of choroidal coloboma. Outline of Cases. This is a case series of five
patients with CHC and RD who were successfully operated using one of two
different surgical techniques: pars plana vitrectomy (PPV) + silicone oil
internal tamponade and/or scleral buckle with encircling band with laser
photocoagulation (SB+EB+LPC) around the coloboma. The purpose of this paper
is to present how to successfully handle patients with CHC, who have
concurrent retinal detachment in the same eye and to compare two different
techniques and indications for the predominant use of one of them in a
specific case. Conclusion. Both surgical techniques can be applied with equal
success in the operation of retinal detachment in eyes with the chorioidal
coloboma. Which one will be used depends only of the posterior segment of eye
findings. We use scleral buckling in cases with RD accompanied by CHC when
the peripheral break is evident and there are no breaks in the coloboma
itself. We also perform, 2-3 days after surgery, laser burns around the
coloboma, which is our modification of this technique. In all other cases it
is indicated to perform PPV+silicon oil internal tamponade.
